NIC card shows different IP address than I assigned it in Server 2003

I have a server running windows server 2003 and IIS 6.0.

I have around 40 IP addresses assigned to the NIC for the different web sites I'm hosting.

The static IP address of the nic is manually set to xxx.xx.xx.3

When I check the "support tab" of the Local Area Connection dialogue box, the box shows the following:

Address Type:   Manually Configured
IP Address    :   xxx.xx.xx.56

My server is running a little slow, but all the web sites come up fine, and everything seems to be working, albeit a bit slower than usual.  Why is there a different IP address showing up in that field, instead of the xxx.xx.xx.3 that I assigned in the TCP/IP settings?

All of the other IP addresses are added under the "Advanced TCP/IP settings".

Also, on my old 2000 server, the node type was set to "Broadcast"  The nic now (same machine & hardware, new OS) is showing the node type as "unknown".  Any ideas on these problems?  Thanks in advance!

I had this - speciifically the unknown node type. It caused problems with the master browser service. That could be why it appeasr slow. I don't think the NIC IP address is an issue - windows tends to make it up as it goes along.

B) Your Server has this issue which may be causing your problem. When you use the Ipconfig.exe utility with the /all switch that shows the TCP/IP configurations on your computer, the node type may appear as "unknown"

B-1 To resolve this issue, use Registry Editor (Regedit.exe) to locate the following key in the registry:


Change the value of the EnableProxy value in the preceding registry key to 0, quit Registry Editor, and then restart your server.

References "Ipconfig /All" Command Shows the Node Type as Unknown (310570)"
